Question

I am new to solr, while creating the indexes i am attaching string to database table id

my field in schema.xml as follows

<field name="id" type="string" indexed="true" stored="true" required="true"/>
<uniqueKey>id</uniqueKey>

and i am passing ‘GROUP1’ for id, but it is storing [B@1e090ee like this.

How could i store the same value(GROUP1) instead of [B@1e090ee ?

Please help

Answer 1

Is group_id string or some numeric data type?
If it’s not string you need to cast it to char before concatenation with appropriate encoding.

Also add encoding (that matches your MySQL db encoding) parameter to dataSource tag, like this:

<dataSource 
    driver="com.mysql.jdbc.Driver" 
    url="jdbc:mysql://host/dbname" 
    batchSize="-1" 
    user="username" 
    password="password" 
    readOnly="true" 
    autoCommit="true" 
    encoding="UTF-8" />
